I needed a quick way to convert hexadecimal values into both decimal values and ASCII characters. While I was at it, I added a couple of other options.
Enter the original value in hex, and this tiny app will give you the corresponding values as Byte (8 bit), Word / Decimal (16 bit), Dword (32 bit) and Qword (64 bit), as well as the ASCII characters.
Please note that to run this application, you need to have the Microsoft .Net Framework 4.0 installed.
(You can get the framework for free right here.)
